YGAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 636,080, dated October31, 1899.

' Application ined March 22,1893. Seraing. 674,805. momma.)

To all whom, it may concern.:

Be it known that I, CLARENCE S. STEWARD,

of Chattanooga, in the county of Hamilton,

State of Tennessee, have invented certain new and'useful Improvements inGas-Burners, of which the following is a complete specication, referencebeing had to the accompanying drawings.

The object of my invention is to produce improvements in burners forfacilitating the use of gases that are rich in carbon-such, for example,as acetylene gas-whereby air may be supplied to and commingled with thegas prior to its ignition in such proportion as to promote perfectcombustion. Y

In the accompanying drawings, Figure I is a perspective view of one formof my burner complete. Fig. II is a perspective view of aslightly-modified form of burner. Fig. III is a perspective view of amultiple burner constructed upon the same principle as the burner shownin Figs. I and II. Fig. IV is a central vertical section of thesubject-matter of Fig. I. Fig. Vis a central vertical section of thesubject-matter of Fig. II. Fig. VI is a central vertical section of thesubject-matter of Fig. III. l

Referring to the igures on the drawings, I indicates the head of myburner, which may be made of a piece of steatite, talc, clay, metal, orany suitable material, preferably steatite.

In the single form of burner shown in Figs. I and II the shape of theburner is preferably bulbous; but that may be modified in any respect,as required or preferred.

The head is provided with a collar 2, that aords means of uniting thehead to a source of gas-supply-as, for example, a pillar 3. The collarmay be formed integrally with the head, as shown in Figs. I and II, orit may be formed separately therefrom and united to the head, as by atapered and cemented joint, screw-threads, or other suitable means.

Referring particularly to Figs. I and II, I provide in the top of thehead a recess 4, preferably a transverse recess cutting entirely acrossthe head. The shape of the recess, however, may be modied, thatillustrated being merely a simple form and one which may be convenientlymade. The recess 4 is preferably V-shaped, being defined by walls 5 and6,*inclined toward each other in order to accommodate opposite apertures7 and S, whose inclination is such as to cause columns of commingled airand gas issuing therefrom to impinge against each other at a suitableheight above the recess 4. The apertures and S intercept transverseair-supply apertures 9 and lO,extending transversely through the wall ofthe head. In like manner they may also intercept apertures ll and I2,formed at right angles to the apertures 9 and 10, as shown in Figs. IIand V, for example. Op posite the apertures 7 and 8 I provide mi nutegas-ducts I3,which, communicating with the bore 14 of the collar 2,aiord means of gas-supply to the discharge-orifices 7 and S.

The mode of communication with the bore 14 may be varied. It may, forexample, be made through a conoidal cavity 15, formed by a suitableinstrument in the head of the burner, or itmay be made byobliquely-disposed ramifications 16, originally extending through theouter wall of the head 1 to the interior of the bore 14, but afterwardcemented shut, as clearly shown in Fig. II of the drawings. The twoforms of communication between the ducts 13 and the bore of the collarare presented merely by way of illustration and as indicative of thefact that a variety of modes of 'communication may be employed.

In Figs. III and VI of the drawingsI illustrate a multiple burnerconstructed upon the principle of the burner above described. In thesefigures, 16 indicates an oblong head provided with a collar 17. The headis provided with a gas-cavity IS, communicating with the bore of thecollar 17. The cavity 18 may be formed by a suitable instrument from oneend of the head and may afterward be closed by cement or otherwise, asillustrated in Fig. III of the drawings. 19 indicates a trough or groovein the upper face of the head, upon opposite sides of which are formedair-supply apertures 20, consisting of holes drilled longitudinallythrough the head. Other airsupply apertures may be provided than thoseillustrated if the number of flames carried by the head require greatersupply of air than can be afforded by the air-supply aperturesillustrated. At suitable intervals in the groove 19 I provideoppositely-discharging ori- ICO tices 2l. These orifices intercept theair-supply apertures 2O and communicate through them with gasducts 22,that afford communication with the interior of the gas-cavity 18. n

In the drawings two oppositely-discl1arging orifices 2l are illustrated;but a greater number may be supplied if more than two flames to eachhead are required.

In operation gas from a suitable source is supplied under pressure tothe bore 14 of the collar of the burner. Thence passing to the gas-ductsit issues in a ne stream to the interior of the gas-supply aperture,where coinmingling with air it passes outwardly through the apertures 7and S of the single burner or through the apertures 2l of the multipleburner. Issuing from the apertures above described the columns of commingled gas and air are ignited and, impi nging against one another,form a fiat and well-dispersed brilliant dame.

It may be noted in this connection that the orifices for the dischargeof commingled gas and air are formed in the wall of the burner-headitself without employment of tips or projecting members of any sortwhatsoever.

That I claim is- 1. The combination with a substantially cylindricalburner-head provided across the top with a transverse V-shaped recessand with a bore,of gas-d ucts, communicating with the bore anddischarging oppositely through the inclined walls of the recess in theburnerhead, substantially as set forth.

2. The combination with a substantially cylindrical burner-head providedacross the top with a transverse V-shaped recess, a bore, and gas-ductscommunicating with the bore, of oppositely-discharging orifices in theinclined walls of the recess opposite the respective ducts,substantially as set forth.

3. A multiple burner, consisting of a head provided with a plurality ofpairs of oppositely-discharging orilices, an internal gascavity,gas-ducts communicating with the orifices, respectively, and means ofair-sup ply to the respective orifices, substantially as set forth.

4. A multiple burner, consisting of a head provided with a cavity, aplurality of pairs of oppositely-discharging orifices, and gas-ductscommunicating between said orifices and the cavity, and air supplyapertures, each of whichcommunicates With a plurality of oriiices,substantially as set forth.

In testimony of all of which I have hereunto subscribed my name.
